Twenty-nine people - including a woman pregnant with twins - were killed in the Omagh bomb.

On Friday, barrister Brian Fee QC said both McKevitt and Campbell now intended to apply to contest the Court of Appeal's decision at the Supreme Court.

He declined to set out any potential grounds of challenge until further legal instructions have been received.

During the hearing at the Court of Appeal the plaintiffs were also awarded costs against McKevitt and Campbell.

Both men are legally aided in a case where fees have been estimated at running into several hundred thousand pounds.

No-one has been successfully criminally convicted of the Real IRA bomb attack which devastated the County Tyrone market town.

But McKevitt, a convicted Real IRA leader serving a 20-year jail sentence; Campbell, a farmer from County Louth currently fighting extradition to Lithuania over an alleged arms smuggling plot; Mr Murphy, a Dundalk-based builder and publican; and Mr Daly, from Culaville, County Monaghan, were all found liable for the bombing in a civil ruling delivered in June 2009.
